Since air becomes less dense with increasing altitude, the wing must encounter more air molecules to maintain the same amount of lift and to do that, it has to go faster relative to the oncoming air. I know this is not explaining it in conventional engineering terms, but I believe it will hold water. Someone will tell me if it doesn't hold water and consequently I'll be all wet.

Is this reasonable, and more importantly LSA compliant?
